[0053] The pressure cooker in the related art has an exhaust valve. When the pressure cooker is used for pressure cooking, the exhaust valve can seal the exhaust hole of the pressure cooker to ensure the pressure inside the pressure cooker. When it is necessary to cook without pressure, the exhaust valve needs to be opened to connect the exhaust hole with the external space of the pressure cooker. However, the current pressure cooker cannot automatically switch between pressure cooking and pressure-free cooking.

[0054] See also Figures 1 to 10A cooking device 100 according to an embodiment of the utility model comprises a pot body 10, a pot cover 20, a first exhaust passage 321, a second exhaust passage 514, an exhaust valve 31, a movable member 50 and a driving assembly 40. A cooking cavity 11 is provided in the pot body 10. The pot cover 20 is connected to the pot body 10. The exhaust valve 31 is movably provided on the pot cover 20, and the exhaust valve 31 is used to open and close the first exhaust passage 321. When the first exhaust passage 321 is opened, the cooking cavity 11 communicates with the outside of the cooking cavity 11 through the first exhaust passage 321.

[0055] The movable member 50 is movably disposed on the pot cover 20, and the movable member 50 is used to open and close the second exhaust passage 514. When the second exhaust passage 514 is opened, the cooking cavity 11 communicates with the outside of the cooking cavity 11 through the second exhaust passage 514. The driving assembly 40 is disposed on the pot cover 20, and the driving assembly 40 is configured to simultaneously enable the exhaust valve 31 to open the first exhaust passage 321 and enable the movable member 50 to open the second exhaust passage 514.

[0056] In the above-mentioned cooking appliance 100, the driving component 40 can simultaneously cause the exhaust valve 31 to open the first exhaust channel 321 and the movable part 50 to open the second exhaust channel 514, thereby increasing the exhaust area under pressure-free cooking, and further realizing the scenario of pressure-free cooking without opening the pot cover 20.

[0057] Specifically, the pot body 10 and the pot cover 20 are hinged or detachably connected by a hinge, and the exhaust valve 31, the movable member 50 and the driving assembly 40 can all be arranged on the pot cover 20. The upper end of the cooking cavity 11 has an opening. When the cooking utensil 100 is working, the pot cover 20 closes the pot body 10 to close the opening of the cooking cavity 11, so that the cooking cavity 11 forms a relatively sealed cavity. When the pot cover 20 opens the pot body 10, the opening of the cooking cavity 11 is also opened.

[0058] Optionally, the cooking appliance 100 further includes an exhaust valve core 32, and the exhaust valve core 32 is provided with a first exhaust passage 321. The exhaust valve 31 is provided at the top of the exhaust valve core 32, and is used to open and close the outlet of the first exhaust passage 321. When the pot cover 20 is closed on the pot body 10, the first exhaust passage 321 can be communicated with the cooking cavity 11. When the exhaust valve 31 opens the first exhaust passage 321, the cooking cavity 11 communicates with the outside of the cooking cavity 11 through the first exhaust passage 321, so that the pressure in the cooking cavity 11 can be discharged through the first exhaust passage 321. When the exhaust valve 31 closes the first exhaust passage 321, the cooking cavity 11 cannot communicate with the outside of the cooking cavity 11 through the first exhaust passage 321.

[0059] Optionally, the exhaust valve 31 may be a pressure limiting valve, which may open when the pressure in the cooking cavity 11 is greater than a pressure limiting threshold of the pressure limiting valve, thereby ensuring the safety of the cooking device 100 to a certain extent. In one example, the pressure limiting threshold of the pressure limiting valve is 70 kPa (kilopascals).

[0060] In one embodiment, when the cooking device 100 performs pressurized cooking, initially, the pressure limiting valve can seal the first exhaust channel 321 under the action of gravity. The gas generated in the cooking cavity 11 enters the first exhaust channel 321, but cannot be discharged from the first exhaust channel 321. As cooking proceeds, when the air pressure in the cooking cavity 11 is greater than the pressure limiting threshold of the pressure limiting valve, the air pressure in the first exhaust channel 321 can lift the pressure limiting valve, and then the gas in the cooking cavity 11 can be discharged through the first exhaust channel 321, achieving a short-term pressure relief effect, and ensuring the safety of the cooking device 100 to a certain extent. When the air pressure in the cooking cavity 11 is lower than the pressure limiting threshold of the pressure limiting valve, the pressure limiting valve reseals the first exhaust channel 321.

[0061] The movable member 50 is movably disposed on the pot cover 20, and the movable member 50 is used to open and close the second exhaust passage 514. When the second exhaust passage 514 is opened, the cooking cavity 11 communicates with the outside of the cooking cavity 11 through the second exhaust passage 514, so that the pressure in the cooking cavity 11 can be discharged through the second exhaust passage 514. When the movable member 50 closes the second exhaust passage 514, the cooking cavity 11 cannot communicate with the outside of the cooking cavity 11 through the second exhaust passage 514.

[0062] Therefore, when the exhaust valve 31 closes the first exhaust passage 321 and the movable member 50 closes the second exhaust passage 514, the cooking device 100 can perform pressure cooking. When the exhaust valve 31 opens the first exhaust passage 321 and the movable member 50 opens the second exhaust passage 514, the cooking device 100 can perform non-pressure cooking.

[0063] The driving assembly 40 is configured to simultaneously enable the exhaust valve 31 to open the first exhaust channel 321 and the movable part 50 to open the second exhaust channel 514. The cooking cavity 11 can be exhausted and depressurized through the first exhaust channel 321 and the second exhaust channel 514, thereby increasing the exhaust area and satisfying the exhaust volume requirement during pressure-free cooking to a certain extent, thereby enabling the cooking appliance 100 to perform pressure-free cooking without opening the lid.

[0064] Optionally, the driving assembly 40 may also cause the exhaust valve 31 to close the first exhaust passage 321 and cause the movable member 50 to close the second exhaust passage 514. In one embodiment, when the driving assembly 40 causes the exhaust valve 31 to close the first exhaust passage 321, the exhaust valve 31 may also be opened when the pressure in the cooking cavity 11 is greater than the pressure limit threshold of the exhaust valve 31, thereby improving the safety of the cooking appliance 100.

[0065] In some embodiments, the driving assembly 40 includes a driving member 41 and an acting member 42 , wherein the driving member 41 is connected to the acting member 42 , and the driving member 41 is configured to drive the acting member 42 to switch back and forth between the first position and the second position.

[0066] When the action member 42 is in the first position, the exhaust valve 31 closes the first exhaust passage 321, and the movable member 50 closes or opens the second exhaust passage 514;

[0067] When the operating member 42 is at the second position, the operating member 42 can simultaneously enable the exhaust valve 31 to open the first exhaust passage 321 and enable the movable member 50 to open the second exhaust passage 514 .

[0068] Thus, the exhaust valve 31 can open the first exhaust passage 321 through the operating member 42 , while the movable member 50 can open the second exhaust passage 514 .

[0069] Specifically, the driving member 41 can drive the acting member 42 to switch back and forth between the first position and the second position, thereby switching the first exhaust channel 321 and the second exhaust channel 514 .

[0070] Please combine Figure 2 , Figure 4 , Figure 5 , Figures 7 to 10 When the active member 42 is in the first position, the exhaust valve 31 closes the first exhaust passage 321, and the movable member 50 closes the second exhaust passage 514, so that the cooking appliance 100 can operate in the pressure cooking stage.

[0071] Please combine Figure 1 and Figure 4 When the active member 42 is in the first position, the exhaust valve 31 closes the first exhaust channel 321, and the movable member 50 can open the second exhaust channel 514. At this time, the cold air in the cooking cavity 11 can be discharged through the second exhaust channel 514, which can improve the heating efficiency of the cooking appliance 100 to a certain extent.

[0072] Please combine Figure 3 and Figure 6When the actuating member 42 is in the second position, the actuating member 42 can simultaneously enable the exhaust valve 31 to open the first exhaust passage 321 and the movable member 50 to open the second exhaust passage 514, so that the cooking appliance 100 can operate in the pressure-free cooking stage.

[0073] In some embodiments, the action member 42 includes a main body 44 and a protrusion 43, the main body 44 is connected to the driving member 41, and the protrusion 43 is disposed on the main body 44;

[0074] When the action member 42 is at the first position, the projection 43 is separated from the exhaust valve 31, and the exhaust valve 31 closes the first exhaust passage 321;

[0075] When the operating member 42 is at the second position, the protrusion 43 lifts the exhaust valve 31 so that the exhaust valve 31 opens the first exhaust passage 321 .

[0076] Thus, the exhaust valve 31 can open and close the first exhaust passage 321 through the action between the bump 43 and the exhaust valve 31 .

[0077] Specifically, in Figures 1 to 10 In the embodiment, the driving member 41 can drive the acting member 42 to move in the left-right direction to switch back and forth between the first position and the second position. One end of the main body 44 is connected to the driving member 41, and the other end is connected to the protrusion 43.

[0078] In one embodiment, when the action member 42 is in the first position, the protrusion 43 is separated from the exhaust valve 31, and the exhaust valve 31 can close the first exhaust channel 321 under its own weight. After the driving member 41 drives the main body 44 to drive the protrusion 43 to switch from the first position to the second position (such as driving the protrusion 43 to move from left to right), the protrusion 43 lifts the exhaust valve 31 so that the exhaust valve 31 opens the first exhaust channel 321.

[0079] Optionally, the driving member 41 includes but is not limited to a linear motor, a cylinder, a hydraulic cylinder, etc. The opening and closing of the driving member 41 can be controlled by, but is not limited to, the cooking appliance 100 according to a cooking program, the user controls by a button, etc. The main body 44 can include but is not limited to a push rod.

[0080] In some embodiments, the action member 42 is provided with an escape space 421 along the thickness direction;

[0081] When the action member 42 is at the first position, the avoidance space 421 corresponds to the movable member 50 along the thickness direction of the action member 42, and the movable member 50 is configured to extend into the avoidance space 421 when rising so that the movable member 50 closes the second exhaust passage 514;

[0082] When the acting member 42 is at the second position, the acting member 42 blocks the movable member 50 from rising in the thickness direction so that the movable member 50 opens the second exhaust passage 514 .

[0083] Therefore, the position of the movable member 50 can be controlled by the action member 42 and the avoidance space 421 .

[0084] Specifically, please combine Figures 1 to 11 In one embodiment, the avoidance space 421 is in the form of a through hole. It is understood that in other embodiments, the avoidance space 421 may also be in the form of a blind hole, a recess, or a groove.

[0085] exist Figures 1 to 11 The thickness direction of the action member 42 is the vertical direction. The action member 42 includes a main body 44 and a protrusion 43. The main body 44 is provided with an escape space 421 along the vertical direction. The protrusion 43 is provided on the surface of the main body 44 away from the cooking cavity 11.

[0086] When the action member 42 is in the first position, the avoidance space 421 corresponds to the movable member 50 along the thickness direction of the action member 42, so that the movable member 50 can extend into the avoidance space 421 when rising, so that the movable member 50 closes the second exhaust channel 514. Optionally, during the pressure cooking process, the action member 42 is in the first position, and the exhaust valve 31 closes the first exhaust channel 321. The movable member 50 can rise and extend into the avoidance space 421 under the force of other structural members, or the movable member 50 can be lifted up and extended into the avoidance space 421 by the pressure in the cooking cavity 11 when the pressure in the cooking cavity 11 is increased, so that the second exhaust channel 514 is closed, and the cooking cavity 11 cannot be exhausted through the first exhaust channel 321 and the second exhaust channel 514, and the cooking device 100 can perform pressure cooking.

[0087] During the pressure-free cooking process, the action member 42 is at the second position, and the exhaust valve 31 opens the first exhaust passage 321. The movable member 50 can withdraw from the avoidance space 421 under the force of the action member 42 and cannot rise under the obstruction of the action member 42, thereby opening the second exhaust passage 514, and the cooking cavity 11 can be exhausted through the first exhaust passage 321 and the second exhaust passage 514, and the cooking device 100 can perform pressure-free cooking.

[0088] In some embodiments, the cooking appliance 100 includes a first float assembly 5151, the first float assembly 51 is disposed on the pot cover 20, and the movable member 50 includes a first float 511 of the first float assembly 51, or;

[0089] The cooking appliance 100 includes a one-way valve assembly 52 , which is disposed on the pot cover 20 , and the movable member 50 includes one-way valves 521 521 of the one-way valve assembly 52 .

[0090] Thus, the function of the movable member 50 can be realized by the first float 511 or the one-way valve 521 .

[0091] Specifically, please combine Figure 1 In one embodiment, the cooking appliance 100 includes a first float assembly 51. The first float 511 can be located at a lower position when there is no pressure in the cooking cavity 11 (zero pressure), and at this time, the first float 511 opens the second exhaust passage 514. At the beginning of cooking, the cold air in the cooking cavity 11 can be discharged through the second exhaust passage 514, thereby improving the heating efficiency of the cooking appliance 100.

[0092] When the action member 42 is in the first position, the escape space 421 corresponds to the first float 511 in the vertical direction, and the exhaust valve 31 closes the first exhaust passage 321. When the pressure in the cooking cavity 11 is increased, the pressure in the cooking cavity 11 can push up the first float 511 to a higher position, so that the first float 511 extends into the escape space 421, thereby closing the second exhaust passage 514, and the cooking device 100 can perform pressurized cooking. In addition, when the first float 511 is at a higher position, it can indicate that the pressure in the cooking cavity 11 is increased.

[0093] When the action member 42 is in the second position, the action member 42 blocks the first float 511 from rising in the up-down direction, and the exhaust valve 31 opens the first exhaust passage 321. When the pressure in the cooking cavity 11 is increased, the pressure in the cooking cavity 11 can lift up the first float 511. When the first float 511 rises and is blocked by the action member 42, it cannot continue to rise, so that the first float 511 continues to keep the second exhaust passage 514 open, and the cooking device 100 can perform pressure-free cooking.

[0094] Generally, the cooking device 100 with a pressure cooking function has a float assembly. The embodiment of the utility model uses the first float 511 as the movable part 50, thereby reducing the use of structural parts, simplifying the structure of the cooking device 100, and reducing costs.

[0095] Please combine Figures 5 to 10 In one embodiment, the cooking appliance 100 includes a one-way valve assembly 52. ​​The one-way valve 521 can be used as the movable member 50. The one-way valve assembly 52 can make the one-way valve 521 have a tendency to move upward. When the action member 42 is in the first position, the avoidance space 421 corresponds to the one-way valve 521 in the up and down directions, and the one-way valve 521 can move upward and extend into the avoidance space 421, thereby closing the second exhaust passage 514, and the exhaust valve 31 also closes the first exhaust passage 321, so that the cooking appliance 100 can perform pressure cooking.

[0096] When the action member 42 is in the second position, the action member 42 blocks the one-way valve 521 from rising in the up and down directions, so that the one-way valve 521 opens the second exhaust passage 514, and the exhaust valve 31 also opens the first exhaust passage 321, so that the cooking appliance 100 can perform pressureless cooking.

[0097] In some embodiments, please combine Figures 5 to 10 In the case where the cooking appliance 100 includes the one-way valve assembly 52 , the cooking appliance 100 includes a second float assembly 53 , which is disposed on the pot cover 20 , and includes a second float 531 movably connected to the pot cover 20 .

[0098] Therefore, the second float assembly 53 can be used to discharge the cold air in the cooking cavity 11 at the beginning of cooking, indicating that the cooking cavity 11 is pressurized.

[0099] Specifically, the cooking appliance 100 includes a second float assembly 53, and the second float assembly 53 may include a third exhaust passage 531. The second float 531 may be located at a lower position when there is no pressure in the cooking cavity 11 (at zero pressure), and at this time, the second float 531 opens the third exhaust passage 531. At the beginning of cooking, cold air in the cooking cavity 11 may be exhausted through the third exhaust passage 531, thereby improving the heating efficiency of the cooking appliance 100.

[0100] When the pressure in the cooking cavity 11 is increased, the pressure in the cooking cavity 11 can push up the second float 531 to a higher position, thereby indicating that the pressure in the cooking cavity 11 is increased.

[0101] In some embodiments, please combine Figures 1 to 10 as well as Fig.12 A first guiding slope 522 is provided at one end of the one-way valve 521 away from the cooking chamber 11, and a second guiding slope 422 is provided on the side wall of the avoidance space 421;

[0102] When the action member 42 moves from the first position to the second position, the second guide slope 422 and the first guide slope 522 cooperate with each other, so that the action member 42 drives the one-way valve 521 to move toward the cooking chamber 11, thereby causing the one-way valve 521 to open the second exhaust passage 514.

[0103] When the actuating member 42 moves from the second position to the first position, the one-way valve assembly 52 is configured to drive the one-way valve 521 to move in a direction away from the cooking cavity 11 , so that the one-way valve 521 closes the second exhaust passage 514 .

[0104] In this way, it is convenient for the acting member 42 to drive the movable member 50 to move.

[0105] Specifically, the one-way valve assembly 52 is disposed on the pot cover 20, and the first guide slope 522 and the second guide slope 422 can be disposed in parallel. Figure 2 , Figure 5 , Figures 7 to 10 and Fig.12 When the action member 42 is in the first position, the one-way valve 521 extends into the avoidance space 421, and the one-way valve 521 closes the second exhaust passage 514. At this time, the first guide inclined surface 522 and the second guide inclined surface 422 are arranged opposite to each other.

[0106] During the movement of the action member 42 from the first position to the second position (eg Figure 5 The second guide bevel 422 is connected to the first guide bevel 522 in cooperation with each other, and the second guide bevel 422 acts on the first guide bevel 522 to generate a downward force on the one-way valve 521, so that the action member 42 can drive the one-way valve 521 to move in a direction close to the cooking cavity 11 (such as downward movement), thereby causing the one-way valve 521 to open the second exhaust channel 514.

[0107] During the movement of the action member 42 from the second position to the first position (eg Figure 6 The second guide slope 422 moves to the left, eliminating the obstacle of the one-way valve 521 moving upward. The one-way valve assembly 52 can drive the one-way valve 521 to move away from the cooking cavity 11 (upward), so that the one-way valve 521 closes the second exhaust channel 514.

[0108] In certain embodiments, the first float assembly 51 or the second float assembly 53 includes a first seal 512 and a float seat 513;

[0109] A first seal 512 is disposed at one end of the first float 511 or the second float 531 close to the cooking cavity 11 , and a float seat 513 is fixed to the pot cover 20 . The first float 511 or the second float 531 can movably penetrate the float seat 513 .

[0110] Thus, the exhaust passage can be opened and closed by the movement of the float.

[0111] Specifically, please combine Figures 1 to 3 In one embodiment, the cooking appliance 100 includes a first float assembly 51, a float seat 513 is provided with a second exhaust passage 514, a first float 511 can movably penetrate the second exhaust passage 514, and a first seal 512 is provided at one end of the first float 511 close to the cooking cavity 11. When the first float 511 is at a lower position, the first float 511 can open the entrance of the second exhaust passage 514 to open the second exhaust passage 514, and in the early stage of cooking, the cold air in the cooking cavity 11 can be discharged through the second exhaust passage 514.

[0112] When the action member 42 is in the first position, when pressure is generated in the cooking cavity 11, the pressure in the cooking cavity 11 can lift up the first float 511, and the first float 511 is located at a higher position, so that the first float 511 rises and extends into the avoidance space 421, and the first float 511 drives the first sealing member 512 to move upward to seal the entrance of the second exhaust channel 514, thereby closing the second exhaust channel 514.

[0113] When the action member 42 is in the second position, the action member 42 blocks the first float 511 from rising in the up-down direction. When the pressure in the cooking cavity 11 is increased, the pressure in the cooking cavity 11 can push up the first float 511. When the first float 511 rises and is blocked by the action member 42, it cannot continue to rise, so that the first float 511 continues to open the entrance of the second exhaust passage 514, and the second exhaust passage 514 remains open.

[0114] Please combine Figures 5 to 10 In one embodiment, the cooking appliance 100 includes a second float assembly 53, a float seat 513 is provided with a third exhaust passage 531, the second float 531 can movably penetrate the third exhaust passage 531, and a first sealing member 512 is provided at one end of the second float 531 close to the cooking cavity 11. When the second float 531 is at a lower position, the second float 531 can open the entrance of the third exhaust passage 531 to open the third exhaust passage 531, and in the early stage of cooking, the cold air in the cooking cavity 11 can be discharged through the third exhaust passage 531.

[0115] When pressure builds up in the cooking cavity 11 , the pressure in the cooking cavity 11 can lift up the second float 531 , and the second float 531 can be located at a higher position. The second float 531 drives the first sealing member 512 to move upward to seal the entrance of the third exhaust passage 531 , thereby closing the third exhaust passage 531 .

[0116] The first sealing member 512 can improve the performance of the float in sealing the exhaust passage. When the float is at a higher position, it can indicate that the cooking cavity 11 is pressurized.

[0117] In some embodiments, the one-way valve assembly 52 includes a valve seat 523, which is fixed to the pot cover 20. The valve seat 523 is provided with an air flow channel 527. The one-way valve 521 can movably penetrate the air flow channel 527. The air flow channel 527 constitutes at least a part of the second exhaust channel 514. The one-way valve 521 is used to open and close the air flow channel 527.

[0118] Thus, the second exhaust passage 514 may be opened and closed by opening and closing the air flow passage 527 .

[0119] Specifically, the airflow channel 527 constitutes at least a portion of the second exhaust channel 514. When the one-way valve 521 opens the airflow channel 527, the cooking cavity 11 can communicate with the outside of the cooking cavity 11 through the airflow channel 527, and the cooking appliance 100 can exhaust air through the airflow channel 527. When the one-way valve 521 closes the airflow channel 527, the cooking cavity 11 cannot communicate with the outside of the cooking cavity 11 through the airflow channel 527, and the cooking appliance 100 cannot exhaust air through the airflow channel 527.

[0148] In some embodiments, the cooking appliance 100 includes a heating assembly 60 disposed in the pot body 10 and configured to heat the cooking cavity 11 .

[0149] In this way, the pressure in the cooking cavity 11 can be increased.

[0150] Specifically, in one embodiment, the heating assembly 60 is disposed outside the cooking cavity 11 and is used to heat the cooking cavity 11. During pressure cooking and non-pressure cooking, the heating assembly 60 can be activated to heat the cooking cavity 11. During pressure cooking, the air pressure inside the cooking cavity 11 is greater than the air pressure outside, achieving high-pressure cooking. Optionally, the heating assembly 60 includes a heating tube or a heating plate.

[0151] In one embodiment, the action member 42 is located at the first position, and the cooking device 100 can work in a pressurized cooking state.
